You have done black & white before, but I was hoping you would do a B&W quick-edit one of these days…
Don’t know if you remember from the Shades of Brown thread but I’m trying to get back into (digital) B&W after some disappointments, so this one is rather welcome.
I tried a few times to get my head round this “channel mixer” module but yet have to obtain good results with it … I really have to take a closer look at theses modules (color balance & channel mixer).
Thanks for the really good video !
Bonsoir Boris, J’ai regardé avec attention cette vidéo. Je t’ai envoyé un message sur ta chaine youtube auquel tu m’a répondu (Alain).
J’ai appliqué les réglages sur une photo, mais n’arrive pas à traiter le ciel correctement. En rajoutant du contraste, augmentant la tonalité pour faire ressortir les nuages, du grain apparaît. La photo est prise à 100 iso, je ne comprends pas pourquoi ce grain apparaît dans le ciel. Je suis sans solution.
J’aimerai te soumettre mon raw + .xmp. pour que tu me dise peut-être où est mon problème. Est tu d’accord ?
Bonjour, @AlainC . Bienvenue au Forum !
Malheureusement, je ne parle pas français et j’utilise un service de traduction sur Internet :
J’espère que vous comprendrez ma réponse.
Si vous changez beaucoup les couleurs, il peut arriver que vous ayez du bruit, même si vous avez pris des photos avec des valeurs ISO faibles. Dans ce cas, je recommande d’utiliser le module Denoise (profilé) pour éliminer le bruit.
Si vous voulez proposer votre fichier brut, ce forum a une catégorie pour cela :
Vous pouvez y créer un nouveau poste et proposer votre fichier brut et xfc à l’édition. Vous pouvez également y décrire votre problème. Mais en anglais. Il est très important que vous choisissiez une licence libre pour votre fichier, par exemple l’une d’entre elles :
Ensuite, les personnes du forum vous aideront et proposeront également leurs propres modifications. Je serai certainement heureux de consulter votre fichier raw et xcf.
Thank you for your answer. I didn’t realize I copied the wrong column from the translator.
I tried the Denoise module, but the clouds were too smooth. I’ll post it on the forum tomorrow. Concerning the license, you necessarily need one?
Yes, this is important for legal security for your copyrights and that the people who want to edit the raw file have permission to do so.
The CC address I gave is just an example. You can choose one for yourself at Creative Commons. If you can’t make up your mind, the best thing to do is look at some examples in the Play Raw category and decide.
A terrific video, Boris. Really helped me with the color balance module. I have two questions hoping you or others could help with:
First, why does the saturation in slope have much more adjustment room, less room in power, and then very little in offset - you barely adjust saturation to have a big impact. Is there a reference somewhere that explains this?
Second question is about the color pickers. If you use the eyedropper in power, hue and pick the entire image, is it picking the average hue of the mid-tones? In your 4th edit, you pick a small sample on the tree - I don’t understand what the resulting adjustment is doing.
I looked in the manual on the eyedroppers but it wasn’t very clear to me what they do.
@s7habo
This one really freaked me out (positively)
Sensational. I am very happy, recently I somewhat learned color balance module, but what you are dancing with it, is amazing.
So with a bit more digging, I think I now can answer my own question. The photo was too blue, so the picker was used to sample a neutral portion of the photo which then calculated the opposite hue value (180 degree value on the color wheel) and applied that color which, in the case of edit #4, reduces the blue cast not by reducing blue, but by adding more of the opposite color of yellow.
I think it’s the math behind the functions. I’m a little out of my depth here because I’m not an expert. Perhaps we should ask @anon41087856 , who redesigned the module.
Yes
The nice thing about it is that you can do white balance in this way, which you can’t do with the white balance module, especially since you can influence the highlights, midtones and shadows separately to a certain degree.
I forgot to mention that with all three functions you can also go higher than + or - 50% by clicking with the left mouse button on the slider and entering the value manually.
